Tire Number Meaning: How To Read Tire Numbers & Letters

We know the tire number meaning can vary for specific sets of tires, but for the most part, it’s simple to understand what each of the letters and numbers means. For the most part, most tires feature the same layout for each of the letters and numbers, making it easy to understand when you’re shopping for a new set for your Huntington daily driver.

To ensure that you enjoy the safest driving experience around Medford, we suggest you familiarize yourself with the tire letters and tire numbers on your Chevy. Not sure where to begin? We’ve got you covered. Below, we’re going to look at a P215/65R15 95H tire to help you decode what the numbers and letters mean:

Example Tire: P215/65R15 95H

  • P: The “P” means that the tire is a P-Metric tire that’s rated for usage in a passenger vehicle. Some other letters you may say could include “LT” which stands for “light truck” and is intended for usage in light-weight pickup trucks.
  • 215: The next set of numbers is “215” which is referring to the width of the tires. This width is often measured in millimeters so this specific example has a width of 215 millimeters.
  • 65: “65” is the aspect ratio of the tire. The 65 means that the tire’s height from the rim to the tread is equal to 65% of the tire’s width. The larger the aspect ratio, the taller or bigger the sidewalls of the tire will be.
  • R: R stands for “Radial” which is the construction used within the tire’s casing. You may sometimes see the letters “B” or even “D.”
  • 15: The next set of numbers relates to the size of your wheel’s diameter. In this case, the tire has a 15-inch wheel.
  • 95H: Tires have a weight limit rating. Meaning, some times have the ability to carry more weight than others. Additionally, that weight is also related to the maximum speed you should be driving with a specific tire. The last set of numbers and letters refer to the load index and speed rating of a tire.
